Correct Taun. Other distinguishing features between the two females; Salome; Redder crown, wrinkled nose, glandular lumps on neck, smaller size, portly/tubbier shape. Romina; Dull Brown crown, flatter head with distinct ruff around face, smoother nose, larger size, slimmer shape.
Not sure why but I find these two really easy to tell apart compared with the breeding Group at Twycross. Maybe I'll upload a shot of Romina I have, who seems to love the camera!
Ozala/Asante at Twycross are more similar probably because they are half-sisters. In the groups at Howletts I can't tell a lot of them apart because they look similar- particularly all the (related) younger ones.
